Did you know that prehistory ends with the appearance of writing? So is. The story begins around 3800 BC. AND since then it has only evolved. Since the hieroglyphs even messages from WhatsApp.
But before getting to that, it underwent various changes to the supports. The printing press, the typewriter and computers. And that difference more to these last two that he monitor. This item has changed the way of writing and connecting with digital.
It is unthinkable to imagine the Internet and everything related to computers without the presence of this hardware. To learn more about it, understand how it works and thus make a better purchase, we recommend this post.
What is a computer monitor and what is this hardware for?
It is a device designed to visually and updated information on the processes that occur in the computer through the interface. That is to say, the data that the system converts into visual information. Also known as screen, not to be confused with a TV especially today, where the differences are less. Both devices are designed for different purposes and therefore have different characteristics. Until a while ago, the distance between monitors and TV was quite explicit.
The resolution, design and types of connections were different. However, in Today both use high-definition connections and even look quite similar in form. But the truth is that the monitors are made to represent the colors as close as possible to the real ones while televisions enhance them to generate greater attraction. Another difference is response time, that is, the rate at which pixels are updated. This is far superior in computer devices.
In turn the Rate or VRR It is very high on the monitors, it is also one of the factors that can define the quality and price of a product. Although it is estimated that the manufacturers associated with these technologies are working in Smart tv. One of the reasons for this is the number of people using the TV exclusively for video game consoles.
History and Evolution How have computer monitors changed over the years?
like the History and the Prehistory the timeline of the monitors It is divided in two. The technology Cathode ray tube CRT and those of flat screen. The first MDA appeared in nineteen eighty one they were monochromatic, that is, they only showed one color. They were designed for text interfaces of the time. Before long the CGA they already had a chromatic scale thanks to an integrated graphics card.
In the year 1984 IBM develops the EGA monitor that supports up to 16 different colors and a better resolution with respect to its predecessors. Again in 1987 IBM brings to market the monitors with Connection VGA (Video Graphics Array) with the ability to display 256 colors and a maximum resolution of 640 x 480 pixels. Currently many screens and devices have this type of connectors, although updated, admitting 1024 x 768 resolution.
The next generation of computer monitors lacked tube and they worked entirely on Electronic components. The first exponent of these new devices was the plasma screen who worked with tiny fluorescent lights that made up each pixel. They offered a high brightness and definitionalthough they were costly and they consumed a lot of electrical energy. The LCD liquid crystal displays They are the most used today, both in monitors, televisions and mobile devices.
They consume very little and transmit qualities in Full HD. The monitors LED Are composed of diodes of this same technology. And they are sub divided into OLED, AMOLED and super AMOLED. The latter integrates touch detection on the screen. Also, they are brighter and reflect less external light. The latest news regarding this hardware, we can mention not only the curved screens but at flexible. There are several devices that already offer this capacity and it won't take long to get to the PC monitors.
What are the main errors or failures related to the monitor and their possible solutions?
We always recommend that in the event of any failure you contact a specialist or in case of being new with the manufacturer or seller. However, there are some problems they have a simple solution and what can you perform yourself. When purchasing a new screen, verify before connecting that the voltages of this and the electrical installation are the same. In the same way that the connector (VGA, HDMI, DVI) match port of the computer.
In this sense, if you have an additional video card, be sure to connect the cable to it. Since otherwise the screen will appear as offline. If you see the monitor It does not turn on, even when you press the power button, it confirms that the system is not in hibernation or sleep. To do this just press the key "Enter" on the keyboard.
If you notice distortion or unwanted lines when you are using it, check that the cables are properly secured. Another possible cause may be a interference with another device. The multiple connections These types of problems usually cause the same electric current output. If you add a second monitor to your computer you may find that when you move the cursor from one to the other, don't match on the same line. This is because they are not calibrated.
Many graphics card software they solve this problem automatically if they are identical models. Otherwise enter Windows display settings and move one of them to the correct height. Stains on the screen. This is a usual inconvenience in tube monitors. If you still use this type of technology, the best thing is that talking speakers or any other kind of magnets. It may return to normal over time.
The above problem does not affect flat screens. However, LED monitors may suffer from dead pixels. This is usually due to usage time. Unfortunately it only remains to take it with a specialist.
In the LCD screens ghosts exist. It is not a paranormal activity but a prolonged use. It usually happens when one or more pixels show the same color for a long time, that is, a still image. They are visible even when we change it. This it is less common in better quality devices.
List of the best manufacturers of computer monitors you should know
To avoid the latter and many other inconveniences, it is best to buy good quality monitors. In this way, they are more likely to give us a better image and last longer. Also, they are not always the most expensive.
Let's see below the best monitor manufacturers:
Asus
It is a Asian company that since 1989 offers monitors and another type of technology to the entire world. Its high-end products are preferred by gamers given its great quality and speed compared to high definitions and fps.
Acer
The Asus main competition as for monitors. However, it is considered the best option in terms of price-quality ratio. Most of its products are LCD which offers very good performance and image fidelity.
Benq
It is the Second best-selling brand of monitors in the world. This position has been achieved thanks to the 4K products which include sizes up to 34 inches whose color accuracy is incredible. It is a great alternative as long as you have a large desk where it fits.
AOC
Is a manufacturer of screens for monitors and televisions Taiwanese. Both products are of the highest quality. Being the most innovative 4K curved. This will make it unnecessary to add more devices to your computer.
Dell
In this position we find a manufacturer outside Asia. It is a brand U.S what is considered the world's largest provider of monitor displays. In addition, they offer a type of technology called IPS with which it is possible observe the monitor from almost any angle without losing quality.
